AUTOMATIC CAR-STOP.

Specification of Letters Patent.

Patented June 18, 1907. i

Application filed April 8, 1907. Serial No. 367,101.

To all whom, it may concern:

a citizen of the United States, residing at Berwind, in the county ofLas Animas and State of Colorado, have invented a new and usefulAutomatic Car-Stop, of which the following is a specification.

This invention has reference to improvements in'automatic car stops, andits object is to produce means for preventing the cars approaching atipple from crowding thereon when a car is already on said tipple andbeing dumped.

the track.

The invention consists essentially of a pivoted track section in linewith a fixed track so arranged as to receive and support a car and to bemoved through a vertical plane to a sufficient eXtentto dump the carthereon, after which this pivoted section or tipple is returned to itsnormal position and the empty car is allowed to pass on to anothersection of Provision is made by means of suitable stops movable into andout of the path of the carwheels to engage the oncoming cars at a pointsufliciently remote from the tipple to prevent these cars from crowdingthereon and so interfering with the action of the tipple. In order toprovide for such action of the stops, the tipple is connected on oneside to stops sufiiciently close to it to stop a car just before it isready to pass upon the tipple, which stops are operated directly by thetipple, while another set of stops more remote from the tipple, arelocated in active position when the tipple is in inactive position readyto receive a car, and these last named stops are released so as to moveout of the path of an oncoming car when the tipple is moved to theinclined position to dump a car and at the same time throw thestops'nearest the tipple into. active position.

The invention will be fully understood from the following detaileddescription taken in connection with the accompanying drawings formingpart of this specification, in which,-

Figure 1 is a side elevation, partly in section, of the improved carstop mechanism; Fig. 2 is a cross section on the line ac-w of Fig. 1 andFig. 3 is a side elevation of the automatic car stop mechanism in adifferent phase of its operation from that shown in Fig. 1.

. latter are indicated-at 11.

Referring to the drawings, there are shown two parallel side beams 1mountedupon crossbeams 2 and illustrative of the elevated track supportsapproaching a dump. Upon thesev beams 1 are secured tracks 3 of anydesired type, which tracks may be simple bars of rectangular crosssection, as shown in the draw ings, or may be of the ordinary shape usedon railways. U

One section 4 of the track and supporting structure is pivoted upon acrossbar 5 so as to be movable about said bar in avertical plane, andthis track section 4 is of sufficient length to receive a car suitablefor conveying material from some distant point to be deposited at apoint coincident with or adjacent to the track section 4. One end ofsuch a car is indicated at 6. The track section 4 is provided with crossbeams 78 and side beams 9 so that this section 4 may be located betweenthe side beams 1, which may at this point be cut away sufficiently toreceive the section 4. Pivoted in suitable recesses formed in the sidebeams 1 adjacent to one end of the movable section 4 of the track arestop levers 10, one adjacent to one track and the other adjacent to theother track, and the track rails 3 may be recessed .at these points toreceive thelevers 10 so that their upper ends may be brought into linewith the c'ar-wheels, which These levers 10 are suitably shaped, and inthe drawings are indicated as being in the shape of an elongated S, but,of course, they may be other wise shaped as desired to perform theirfunctions. The levers 10 are. so located that while one end 12 maybemoved into the.

path of its respective car-wheel, the other end 13 is normally below thelower edge of the respective side beam 1 of which the lever 10 has itsend 13 connected by a rod 14 to the respective sidejbeam 9 of thesection 4 on the side of the pivot rod 5 which is nearest to the lever10. Now, it will be seen that when the track section 4 is moved from ahorizontal position, as shown in Fig. 1, to an inclined position, asshown in Fig. 3, each rod 14 will be so moved as to draw the end 13 ofthe lever 10 in a direction toward the inclined track section 4. Thismovement will cause the other end 12 of each lever 10 to move into anoperative position where it will be in the path of a car-wheel 11. It,will thus be seen that when arms 17 connected by links or rods 18 to thenext loaded car may be pushedonto the said" tipple.

Now, in order to prevent cars more remote from the tipple from movingtoward the same when the stop levers are in the inactive position, thereis provided another set of stop levers similar to the levers 10 andhaving like upper ends 12 and lower ends 13. Pivotally mounted in theside beams 1 at a point about coincident with the end of the track 3adjacent to the tipple 4 is a rock bar 16 upon which are securedprojecting rock ends 13 of the stop levers 15. The rock bar 16 is alsoprovided with latch-arms 19 having a portion 20 adjacent to the rock bar16 bent into shape to receive the crossbeamS of the vtipple, and beyondthis portion 20 the latch arms 19 are bent into guiding cam exten* sions21. The rock bar 16 is under the constraint of a spring 22 connected atone end to said rock bar 16 and at the other to' the pivot rod 5 of thetipple 4. The tendency of this spring is to rock the bar 16 on itspivots in a direction to elevate the cam ends 21 of the latch arms 19and at the same time to move the stop levers 1 5 into the inactiveposition shown in Fig. 3. The position of the parts just described isonly possible when the tipple is in the inclined position, for when itis moved to the horizontal position the cross beamB engages the camextensions of the latches 19 and causes the rock bar 16 to move on itspivots in a direction against the action of the spring 22 until thecross beam 8 is dropped into the portion 20 designed to receive it.Under these conditions the latch arms 19 have been forced downward torock the bar 16 so as to move the ends 12 of the levers 15 into activeposition in the path of the wheels of an oncoming car. These levers 15are sufliciently remote from the tipple 4 to look all the carsapproaching the le' vers-15 except one car which, when the tipple isbrought to the horizontal position, is released by the levers 10and-permitted to move on to the tipple ready to be dumped;

When the dumping operation takes place the cars more remote from thetipple are released by the levers 15 but are then caught by the levers10', and when the tipple is again brought to the horizontal position allthe cars except the one immediately adjacent to the'levers 10 are againlocked by the levers 15. Thus it will be seen that but one car at a timecan approach the tipple, and this alternate locking and unlocking of thecars one at a time is entirely automatic and can only operate as thetipple is moved. Thus there is no danger of the oncoming cars crowdingon to the tipple and so causing trouble or damage.

I claim 1. An automatic car stop comprising a line of track, atipple-included therein, stop levers movable into and out of the pathsof cars on said track, direct connections'between said levers and thetipple, other levers also movable into and out of the paths of carsonsaid track and located at a point more remote from the tipple than thefirst set of levers, a rock shaft connected to said second set oflevers, a spring tending to hold said rock shaft in a position tomaintain the second set of levers in inactive position, and camlatches'on the rock shaft in the path of the tipple for moving thesecond set of levers into active position.

2. An automatic car stop comprising a line of track, a tipple includedtherein, stop levers adjacent to said tipple and movable intoand out ofthe path of cars on said track,

direct connections between the tipple and the stop levers, another setof stop levers more remote from the tipple than the first set, arockshaft, connections between the same and the second set of stoplevers, a spring connected to said rock shaft and tend- -mg to-move thesame'in a position to maintain the second set of levers in inactiveposition, and latch arms having locking sections to receive a portion ofthe tipple and other cam sections constituting continuations of thelocking sections and arranged to be engaged by the tipple when movedfrom an inclined to a horizontal position.

In testimony that I claim the foregoing as my own, I have hereto afiixedmy signature in the presence of two witnesses.
